PV Mat Manufacturing Improvements for Continuous Roll-to-Roll Amorphous Silicon Module Production
- Energy Conversion Devices, Inc., 1675 West Maple Road, Troy, Michigan 48084 (United States)
Under the PVMat 2A Program, Energy Conversion Devices, Inc. (ECD) has performed manufacturing technology development work utilizing its proprietary continuous roll-to-roll triple-junction a-Si alloy solar cell production line. Among the accomplishments achieved under this program, ECD demonstrated the production of the world{close_quote}s first 4ft{sup 2} PV modules utilizing triple-junction two-bandgap solar cells manufactured in a commercial, continuous roll-to-roll production line. These 4ft{sup 2} modules had 9.5{percent} initial efficiency and 8{percent} stable module efficiency. ECD has recently designed and constructed a 5 MW continuous roll-to-roll a-Si solar cell processor for its U.S. joint venture, United Solar Systems Corp. (United Solar). The state-of-the-art processor incorporates major advances in solar cell design and manufacturing processes achieved by United Solar and ECD, with support from DOE/NREL. The advanced continuous roll-to-roll triple-junction a-Si module production technology will reduce module production costs, increase stabilized module efficiency, and increase commercial production capacity. {copyright} {ital 1997 American Institute of Physics.}
